G. JOHNSON. v Hot-Water Attachment for Magazine-Stoves.

Patented Mar. 30,1880.

ILFETFRS, PNOTO-UTHOGRAPHE. WASHINGTON CHARLES JOHNSON, OF THOROLD, ONTARIO, CANADA.

HOT-WATER ATTACHMENT FOR MAGAZINE-STOVE?- SPECIFICATION forming part of Letters Patent No. 225,987, dated March 30, 1880.

Application filed August 13, 1879.

To all whom it may concern:

Be it known that 1, CHARLES J OI-INSON, of Thorold, in the county of WVelland, in the Province of Ontario, Dominion of Canada, landscape gardener, have invented certain new and useful Hot-Water Attachments to SelfFeeding Base-Burning Stoves; and I do hereby declare that.the following is a full, clear, and exact description of the construction and operation of the same.

The invention relates to improvements in hot-water apparatus for attaching to all kinds of parlor base-burnin g heatin gstoves, whereby dwellings, &c., can be heated by means of hot water in a healthy manner, with no extra cost of fuel to that quantity which is ordinarily used for any base-burning stove.

This invention consists in the combination, in a base-burning stove, of a cylinder having a water-space and an outer tube connected therewith by oppositely-arranged openings, said space being provided with eduction and induction pipes, the cylinder forming the magazine or a portion of the magazine of the stove, all of which will be fully hereinafter described, and pointed out in the claim.

By reference to the annexed drawings, forming part of this specification, it will be seen that Figure 1 represents my hot-water cylinder detached from a stove. Fig. 2 is an upright section through the center of the same. Fig. 3 is a top view. Fig. 4 represents aside view of a base-burning-stove feeder with hot-water cylinder attached. Fig. 5 represents a modification in which the feeder and hot-water cylinder are combined in one. Fig. 6 represents a sectional view of a stove, showing my improvement.

A, Fig. 1, is a hollow metallic cylindrical reservoir having a water-space, O, as shown in Fig. 2, of about one inch all around it. It is beveled outward at its lower end, so as to allow coal to feed freely through it, and is provided with a fiow-pipe, Gr, secured in the usual way and communicating with its waterchamber 0, which extends entirely around it. On the outside of the upper part of the said cylinder A is secured an outer tube, E, halfcircular in form, communicating with the waterspace O bymeans of two openings, F, in each side, respectively, of the outer shell of the cylinder A, as shown at Figs. 2 and 3.

B B B are three lugs attached to the top of the cylinder A, each provided with a hole, by means of which it is secured to the bottom of a base-burning feeder, H, by screws I, (or otherwise, if preferable,) as shown at Fig. 4. 1f the cylinder is to be attached to any baseburning stove in use, the only alteration required is to cutoff afew inches-say about sixfrom the lower part of the feeder, while new stoves can be made with a shorter feeder than now commonly constructed, and only require the cylinder A to be attached to make the feeder the proper length.

Fig. 5 is simply the same cylinder as Fig. 1, only elongated, made of heavier metal, and used in a base-burner instead of the regular magazine. Constructed in this way it is a combined feeder and water cylinder.

The flow and return pipes are attached to it as to the small cylinder A. This plan will work; but I prefer to have the cylinder constructed short and secured to the end of a feeder, where the heat is greatest.

Fig. 6 may represent any ordinary selffeeding base-burning stove having my hot-water cylinder attached to the lower end of the feeder, with the flow and return pipes projecting from said cylinder through the stove, as shown. The said pipes may be made to pass through the illuminating-inicas of the upper stove-doors, or two openings may be cut in the stove at the most convenient place for the pipes to pass through.

It will be observed that I do not show the pipes passing from the stove through the rooms, as they would be put up differently to suit the requirements of various buildings. I may state, however, that in a general way the pipe D would in all probability be passed perpendicularly to the floor, and pass under the same to a vertical wall, while the flow-pipe G would pass to an upper room to heat it, and thence downward and connect with the return-pipe D, by which means there would be a perfect circulation of water, the cool water passing through the pipe D into the cylinder A, and, becoming heated as it rises, passes into the pipe E through the openings F F, thence to the return-pipe G, and so on, without the addition of water for long intervals.

Many advantages attend the use of my device.

It is a well-known fact that air in a dwelling heated by hot-water pipes is more wholesome and pure than when heated by other means.

The heat of one parlor-stove is so utilized that other rooms can be heated with the same amount of coal used to feed one stove; consequently my device is exceedingly economical, more especially when the price of coalis high. The pipes running from the stove, being warm at all hours of the day and night, form a very convenient place for drying and warming clothes without danger of burning them.

The device is perfectly safe in every way, free from danger by fire, and also free from the liability to accident arising from the use of steam-pipes for heating.

My device can be used on any base-burning coal-stove that is a self-feeder, of any size or form, and is especially adapted to heat greenhouses, coach-houses, and other out-buildings economically and successfully.

An advantage in burning coal in a baseburner is had in the fact that the cylinder, being always filled with water, prevents the coal in the lower end of the feeder from becoming ignited, such sometimes taking place under the conditions of a good draft and superior coal.

One of the greatest objections on the score of health to base-burning stoves is the downdraft, circulating the products of combustion around the base of a stove, which, if the same is not perfectly air-tight, allows gas to escape, the most deadly of poisons. This I would prevent by using only the direct draft, and conducting a coil of pipe around the base of a stove, which would heat the air at the floor of a room, the very place where it is wanted to make it comfortable in winter.

I am aware that the lower end of the magazine of a boiler for heating purposes has been constructed with a surrounding water-foot connectin g with a space surroundingthe magazine and combustion-chamber and I am also aware that a heating coil-pipe has been arranged around about the lower portion of a fuel-magazine, and such features I therefore disclaim.

Having thus described my heating apparatus, what I claim as my invention is- The combination, in a base-burning stove, of a cylinder, A, having water-space O, and an outer tube, E, connected therewith by openings F, said space being provided with eduction and induction pipes D G, the cylinder forming the magazine or portion of the magazine of the stove, substantially as specified.

Dated at Hamilton, ()anada this 4th day of March, A. D. 1879.
